Defensive publication

ABSTRACT

POLYOLEFIN COMPOSITIONS, PROTECTED AGAINST METAL INDUCED OXIDATION SUCH AS INCURRED BY COPPER, CONTAIN AS THE STABILIZER SYSTEM THEREFOR A PHENOL ANTIOXIDANT, A NITROGENOUS METAL DEACTIVATOR AND A THIOCIACID ESTER SYNERGIST. EXEMPLARY OF SUCH COMPOUNDS ARE PENTAERYTHRITOL TETRAKIS(3 - (3&#39;&#39;, 5&#39;&#39; - DI-T.BUTYL-4&#39;&#39;-HYDROXYPHENYL)PROPIONATE), 2, 2&#39;&#39;THIODIETHANOL DI-B- (DI-T-BUTYL -4- HYDROXYLPHENYL) PROPIONATE, OXANILIDE, N, N&#39;&#39;-DI-ACETYLADIPIC ACID DIHYDRAZIDE AND DILAURYL THIODIPROPIONATE. THEIR IMPROVED OXIDATION RESISTIVITY RENDERS THEM PARTICULARLY SUITABLE FOR WIRE AND CABLE INSULATION.

Cl.260-45.85 B No Drawing. 40 Pages Specification Polyolefin compositions,protected against metal induced oxidation such as incurred by copper,contain as the stabilizer system therefor a phenol antioxidant, anitrogenous metal deactivator and a thiodiacid ester synergist.Exemplary of such compounds are pentaeryth'ritol tetrakis- [3 (3,5di-t.butyl-4-hydroxyphenyl)propionate], 2,2- thiodiethanoldi-fi-(3,5-di-t-butyl 4 hydroxylphenyDpropionate, oxanilide,N,N'-di-acetyladipic acid dihydrazide and dilauryl thiodipropionate.

Their improved oxidation resistivity renders them particularly suitablefor wire and cable insulation.
